Using the method, particularly simple, quick, no instrument and the cost-effective assembling of jaw member become possibility.Jaw
The assembly being consequently formed of component can easily be processed further.
According to the fourth aspect of the invention, the open method assembling surgery tubular shaft apparatus.Tubular shaft instrument bag contains
Above-mentioned jaw member, shaft member and actuator lever.Assembling starts from providing the link component of branch towards cam support component
Branch in the state of associated side and cam support component.One branch and cam support component are arranged in two being spaced
In individual parallel plane, and the longitudinal axis of two parts determine the certain angle between it.This is according to the third party of the present invention
Face, to carry out, wherein provides the explanation with regard to the angle of middle employing in this regard.Subsequently, by one branch and cam support
Component introduces one another till its contact.Then, one branch and cam support component are so that its longitudinal axis
Between angle reduce mode relative to each other determine that plane to be rotated up two longitudinal axis via its contact surface
Till at least one respective cams of the cam support component of the both sides in cross point are contacted with the link component of a branch.Method
The opposition side being further disclosed in cam support component connects another branch.However, this also can be before aforementioned method steps
Occur, so that another branch is alternatively installed on the first branch on cam support component.This another branch can be with
To be installed on cam support component as described above for identical mode described in one branch, branch also can completely differently pacify
Dress.When another branch for example should keep fixing, described branch can simply be placed on cam support component, another point
Propping up does not need rotary motion and cam support part between.In the case, cam support component for example can represent two or more
Multiple mushroom protuberances, it can insert the circular hole in the link component of another branch respectively, wherein narrow in the axial direction
Elongated hole to be extended with one fixed width, and described width approximately corresponds to the diameter of the axostylus axostyle of mushroom protuberance.Therefore cam props up
Moving axially relative between support component and another branch is possible, and not generating means any lateral movement each other.
It is also possible to use connection mechanism known to other.In principle it is also possible to not install another branch, because this branch is for example formed
Far-end in shaft member.After installing jaw member, this is inserted in the far-end of shaft member with its near-end.Thus described
One branch and/or another branch and cam support component interfere in shaft member or actuator lever in different time
Individual so that thus corresponding to the fully open position of jaw member position occur cam support component and a branch and/
Or the axial displacement between another branch.If Liang Ge branch is similarly mounted on cam support component, then when it is gone back
About when same time is engaged with shaft member or actuator lever, it is also advantageous.Here preferably, nibbled with shaft member by branch
Merge and cam support component is engaged with stick.Further preferably cam support component first is engaged with actuator lever, thus prevents
Only cam support part displacement axially further proximally.Then, one or more branches can even proximally move further
Position is till it is engaged with shaft member.Therefore, branch preferably comprises proximal extension spring extensions, and it is by branch
Near-end is pushed into the inwall of shaft member.At the inwall towards the side of shaft member, extension has at least one protrusion
Portion, it can enter dimple in shaft member or depths to set up the connection between branch and shaft member.According to having further
Profit development, extension facing away from the inwall of shaft member side, forming region, its to corresponding on cam support component
Surface cooperation so that obtain install when or during installation at least one projection on the extension of branch come into
Dimple in shaft member and when being axially fixed to shaft member by this branch, in branch and cam support component relative displacement
Region at, formed groove so that the extension of branch can not more closely move to the axis of shaft member, the extension of branch
At least one protuberance partly gone up can depart from the dimple completely from shaft member.Due to once connecting in cam support component
When being connected to stick, it no longer can be moved to far-end, and this groove can be saved in the extension of branch, thus reliably passes through axostylus axostyle structure
Part come to prevent dismantle jaw member.
Preferably, at least one link component and cam support component are designed to generally flat and substantially upper strata
Shape ground is overlapping.
Using described method, it is possible to provide tubular shaft apparatus, it can be particularly easy to assemble, and then assembly can not be disassembled
And safely prevent link component from departing from cam support component.
Substitute the said method of two link components of assembling and cam support component, there is other changes.In the first replacement
In variant, two link components can elastic bending in its generally plane of extension.In the case, link component can be at it
Extend in plane and bend, so that not existing overlapping between connecting rod path and the cam of cam support component, then it can draw
It is directed at cam support component.Only when link component is contacted with cam support component, link component relaxes and returns to its original-shape,
Between connecting rod path and cam, wherein then form groove.In the second alternate variation, provide the link component with interruption,
Described interruption is only slightly larger than associated cam.These interruptions are arranged such that to exist cam support component and link component
Positioned opposite, all cams of wherein cam support component are towards corresponding dimple.During here is positioned opposite, link component and cam
Supporting member can be placed in together, and its cam enters in connecting rod path via dimple.In the axial toward each other position of two parts
During shifting, between connecting rod path and cam, then form groove.If the positioned opposite of assembly is located at two parts in normal behaviour
Beyond the region moved each other in work, then it is favourable.In the 3rd alternate variation, link component extends plane perpendicular to it is
Elasticity is pliable.Additionally, link component represents above-mentioned dimple in connecting rod path, be these dimples not with convex
The interval identical of wheel is spaced to arrange.In here change, the link component assembling with cam support component is from extension plane
Bow out, the first cam to be threaded onto first connecting rod path via the first dimple.Then, cam support component and link component are mutual
Axially displaced the second cam until the second dimple on the opposite side till.Now, this second cam carrys out spiral shell via the second dimple
It is bonded to second connecting rod path, this part in wherein connecting rod path flexs back into its home position.If suitably, other are convex further
Wheel is threaded onto connecting rod path in the same manner.The advantage of this change is that do not have cam support component and link component each other relative
Position, two of which part is disassembled to apply elastic deformation without for link component.Therefore, this embodiment guarantees not
Can separate by accident.
